## Performance

- **Batch push notifyBatch()**: Batch push now wakes all waiting workers correctly via `notifyBatch(N)` instead of a single `notify()` call. Each waiter is woken up individually, fixing a bug where only 1 of N workers received jobs immediately.
- **Pre-compiled HTTP route regexes**: All 40+ regex patterns in HTTP route files are now compiled once at module load instead of per-request (~100µs/request savings).

## Security

- **constantTimeEqual timing fix**: Removed early return on length mismatch that leaked token length via timing side-channel.
- **Batch PUSHB data validation**: Individual job data size is now validated in batch push (was only checked in single PUSH), preventing 10MB limit bypass.
- **Dashboard queue name validation**: `GET /dashboard/queues/:queue` now validates queue names like all other endpoints.
- **Error message sanitization**: SQLite/database error messages are no longer leaked to clients in TCP and HTTP error responses.

## Bugfixes

- **Silent error swallowing**: Replaced 7 empty `.catch(() => {})` blocks with proper error logging in addBatcher flush, sandboxed worker stop/kill/restart/heartbeat paths.
